[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] like Figures 1 to 7 As shown, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention includes a floating platform 1, a photovoltaic panel 2, a circular track 3, a walking component 4, a support beam 5, a mobile component 6, a telescopic component 7 and a mounting frame 8. The photovoltaic panel 2 is laid on the floating platform 1, and the circular track 3 is arranged at the edge of the floating platform 1. The circular track 3 is arranged around the photovoltaic panel 2. There are two walking components 4, and the two walking components 4 are arranged on the circular track 3 along the center of the circular track 3. The walking components 4 can walk along the extension direction of the circular track 3. The two ends of the support beam 5 are respectively connected to the two walking components 4, and the mobile component 6 is movably arranged on the support beam 5 along the length direction of the support beam 5. The telescopic component 7 includes a fixed part and a telescopic part 702, the fixed part is connected to the mobile component 6, and the telescopic part 702 is telescopic relative to the fixed part in the vertical direction. The mounting frame 8 is connected to the telescopic part 702, and a suction cup 9 is provided on the end face of the mounting frame 8 that is away from the telescopic component 7 in the vertical direction, and the suction cup 9 is used to adsorb the photovoltaic panel 2.

[0026] When the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is in use, when the photovoltaic panel 2 needs to be replaced, the two walking components 4 move in the same direction along the circular track 3 to drive the support beam 5 to rotate relative to the center of the circular track 3. When the support beam 5 rotates to the top of the photovoltaic panel 2 that needs to be replaced, the movement of the two walking components 4 is stopped, and the moving component 6 moves with the mounting frame 8 in the length direction of the support beam 5 so that the mounting frame 8 can be moved to the top of the photovoltaic panel 2 that needs to be replaced. Then the telescopic part 702 of the telescopic member 7 is controlled to extend so that the suction cup 9 on the mounting frame 8 is adsorbed on the upper surface of the photovoltaic panel 2 that needs to be replaced, and the telescopic part 702 of the telescopic member 7 is controlled to shrink so that the photovoltaic panel 2 is separated from the floating platform 1. Finally, the mobile component 6 is used to move the adsorbed photovoltaic panel 2 to the edge of the floating platform 1, and then the suction cup 9 is used to adsorb the qualified photovoltaic panel 2, and the qualified photovoltaic panel 2 is moved to the position of the disassembled photovoltaic panel 2 by the mobile component 6 for installation, thereby completing the replacement of the photovoltaic panel 2.

[0027] The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention can quickly locate the position of the photovoltaic panel 2 that needs to be replaced through the cooperation of the walking component 4 and the moving component 6, which facilitates the replacement of the photovoltaic panel 2 and greatly improves the replacement efficiency of the photovoltaic panel 2. The traditional replacement of photovoltaic panels 2 requires manual climbing and operation. The present invention realizes automatic replacement through mechanical devices, reduces manpower input, labor intensity and safety risks. The photovoltaic panel 2 is adsorbed by the suction cup 9 to avoid dangerous situations such as slipping and collision that may occur during manual operation.

[0028] In some embodiments, a 3D sensor 10 is further provided on the mounting frame 8 , and the 3D sensor 10 is used to scan defect information of the photovoltaic panel 2 .

[0029] The 3D sensor 10 can scan the photovoltaic panel 2 and collect three-dimensional data of its surface. Through these data, defects such as cracks, bends, and dirt accumulation of the photovoltaic panel 2 can be accurately detected. Before replacing the photovoltaic panel 2, the 3D sensor 10 can monitor the status of the photovoltaic panel 2 in real time and evaluate the degree of damage and the necessity of replacement. The 3D sensor can also collect key parameters such as the size and shape of the photovoltaic panel 2 to provide accurate data support for the replacement operation. Combined with the walking component 4 and the moving component 6, the 3D sensor 10 can help automatically locate the defect position on the photovoltaic panel 2 and improve the accuracy of detection and replacement.

[0030] Compared with traditional manual visual inspection or simple two-dimensional image detection, the 3D sensor 10 can provide more accurate defect information, which helps to more accurately evaluate the condition of the photovoltaic panel 2. Through real-time monitoring of the photovoltaic panel 2, the operation and maintenance personnel can make more scientific and reasonable maintenance decisions based on the data provided by the 3D sensor 10, avoiding excessive maintenance or delayed maintenance. Through real-time monitoring and automatic defect positioning, the operation and maintenance team can respond quickly and replace damaged photovoltaic panels 2 in a timely manner, thereby reducing the downtime of the power generation platform and improving power generation efficiency. Regular inspection and timely replacement of damaged photovoltaic panels 2 can effectively extend the overall service life of the photovoltaic power generation platform.

[0031] In some embodiments, the walking assembly 4 includes a walking frame 401, a first roller 402, a first rotating shaft 403 and a first motor 404. The first roller 402 is rotatably connected to the walking frame 401 through the first rotating shaft 403, and an annular groove 4021 is provided on the outer peripheral surface of the first roller 402. The annular groove 4021 is arranged around the axial direction of the first roller 402, and the annular groove 4021 is mounted on the circular track 3 and can roll along the extension direction of the circular track 3. The first motor 404 is connected to the first rotating shaft 403 in a transmission manner to drive the first rotating shaft 403 to rotate, and both ends of the support beam 5 are connected to the walking frame 401.

[0032] like Figure 2 and Figure 6 As shown, the first roller 402 is rolled by the rotation of the first rotating shaft 403, thereby pushing the walking assembly 4 to move along the circular track 3. The cooperation between the annular groove 4021 and the circular track 3 ensures the stability and directional movement of the walking assembly 4 on the track, and avoids lateral sliding. The first motor 404 drives the first rotating shaft 403 through the transmission system, and then drives the first roller 402 to rotate, so as to realize the walking action of the walking assembly 4. Both ends of the support beam 5 are connected to the walking frame 401, which enables the support beam 5 to remain stable when the walking assembly 4 moves, and also facilitates the transmission of the moving power of the walking assembly 4.

[0033] The design of the walking frame 401 and the close fit between the roller and the track ensure the stability of the walking component 4 during movement. The design of the annular slot 4021 allows the walking component 4 to move accurately along the annular track, thereby improving the positioning accuracy. The modular design of the walking component 4 makes maintenance and replacement of components more convenient and quick, and the roller driven by the motor achieves smooth rolling motion, thereby improving motion efficiency and reducing energy consumption. As a result, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention is more flexible, efficient and stable, providing important guarantees for the operation and maintenance of offshore photovoltaic power generation.

[0034] In some embodiments, the travel assembly 4 further includes a first gear 405 and a second gear 406 . The first gear 405 is mounted on the output shaft of the first motor 404 , and the second gear 406 is mounted on the first rotating shaft 403 and meshes with the first gear 405 .

[0035] like Figure 3 and Figure 6 As shown, when the first motor 404 is started, it drives the first gear 405 to rotate through its output shaft. The first gear 405 is meshed with the second gear 406. When the first gear 405 rotates, it transmits power to the second gear 406 through meshing. The second gear 406 is mounted on the first rotating shaft 403. As the second gear 406 rotates, the first rotating shaft 403 also rotates, thereby driving the first roller 402 to rotate. The first roller 402 rolls through the rotation of the first rotating shaft 403, pushing the walking assembly 4 to move along the circular track 3.

[0036] The gear transmission system has high transmission accuracy, which helps the walking assembly 4 to move accurately on the track. The gear transmission system has good sealing performance, which can reduce the impact of the external environment on the walking assembly 4 and improve the reliability of the system. The gear system is relatively simple, and it is usually easier to maintain and replace gear components. The floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention adds the first gear 405 and the second gear 406, so that the power transmission system of the walking assembly 4 becomes more efficient and reliable.

[0037] In some embodiments, the floating offshore photovoltaic power generation platform 100 of the embodiment of the present invention further includes a lifting assembly 11, which is disposed between the traveling frame 401 and the support beam 5, and is used to drive the support beam 5 to rise and fall.

[0038] Specifically, during the working process, the operation and maintenance personnel can ride on the mounting frame 8 through the lifting and lowering of the lifting assembly 11, reach the position where the photovoltaic panel 2 needs to be replaced by moving the mounting frame 8, and then replace the photovoltaic panel 2. Thus, through the mechanized lifting operation, the risk of direct climbing and manual operation by the operation and maintenance personnel can be reduced, and the work safety can be improved. The introduction of the lifting assembly 11 can reduce the time required to replace the photovoltaic panel 2 and further improve the operation and maintenance efficiency. The lifting assembly 11 can make the support beam 5 adapt to different heights, increasing the adaptability of the platform.

[0039] In some embodiments, the lifting assembly 11 includes an inner sleeve 1101, an outer sleeve 1102, a first closing plate 1103, a second closing plate 1104, a second motor 1105 and a screw 1106. The inner sleeve 1101 is arranged on the walking frame 401 in the vertical direction, the first closing plate 1103 is arranged on the top port of the inner sleeve 1101, and a threaded hole is provided on the first closing plate 1103. The outer sleeve 1102 is sleeved on the inner sleeve 1101 and can be slidably matched with the inner sleeve 1101 in the vertical direction. The second closing plate 1104 is arranged on the top port of the outer sleeve 1102, and a through hole is provided on the second closing plate 1104, and the screw 1106 passes through the through hole and is threadedly connected with the threaded hole. The second motor 1105 is arranged on the second closing plate 1104 and is connected to the screw 1106, and the support beam 5 is connected to the outer sleeve 1102.

[0040] Specifically, when the lifting assembly 11 is working, when the second motor 1105 is started, it drives the screw 1106 to rotate. Since the screw 1106 is connected to the threaded hole on the first sealing plate 1103, the rotation of the screw 1106 will be converted into a lifting motion, and the outer sleeve 1102 is lifted in the vertical direction, and then the outer sleeve 1102 drives the support beam 5 to lift. The cooperation of the inner sleeve 1101 and the outer sleeve 1102 provides guidance and support, ensures the linearity of the lifting action, and prevents lateral movement. The first sealing plate 1103 and the second sealing plate 1104 are respectively located at the top of the inner sleeve 1101 and the outer sleeve 1102, which can play the role of sealing and fixing the lifting assembly 11, prevent the leakage of lubricating oil or other media, and maintain the stability of the lifting mechanism. By controlling the start, stop and speed of the second motor 1105, the lifting speed and position of the support beam 5 can be accurately controlled to achieve fine lifting control. Driven and threaded by the second motor 1105, the lifting assembly 11 can provide accurate lifting control. The design of the inner sleeve 1101 and the outer sleeve 1102 provides stable guidance and support, ensuring the stability of the platform during the lifting process.

[0041] In some embodiments, a groove 501 extending along the length direction of the support beam 5 is provided on the top surface thereof, and the moving assembly 6 includes a moving frame 601, a second roller 602, a second rotating shaft 603, and a third motor 604, and the second roller 602 is rotatably connected to the moving frame 601 through the second rotating shaft 603. Part of the second roller 602 is located in the groove 501, and the outer wall surface of the second roller 602 stops at the bottom wall of the groove 501, the third motor 604 is connected to the second rotating shaft 603 in a transmission manner, and the moving frame 601 is connected to the fixed portion of the telescopic rod.

[0042] Specifically, when the third motor 604 is started, it drives the second roller 602 to rotate, and since part of the second roller 602 is located in the groove 501, the rotation of the second roller 602 causes the moving assembly 6 to move along the length direction of the support beam 5. The outer wall surface of the second roller 602 contacts the bottom wall of the groove 501, and this cooperation ensures the stability and linearity of the moving assembly 6 on the support beam 5.

[0043] The cooperation between the groove 501 and the second roller 602 increases the stability during the movement and reduces the lateral movement and vibration. The rolling motion of the second roller 602 can significantly reduce the friction force compared to the sliding friction and improve the movement efficiency. The design of the mobile component 6 is easy to maintain and replace, which reduces the operation and maintenance cost. The mobile component 6 makes the operation on the support beam 5 more flexible and can quickly respond to the replacement and maintenance needs of the photovoltaic panel 2.

[0044] In some embodiments, the moving assembly 6 further includes a third gear 605 and a fourth gear 606 . The third gear 605 is sleeved on the output shaft of the third motor 604 , and the fourth gear 606 is sleeved on the second rotating shaft 603 and meshes with the third gear 605 .

[0045] Specifically, Figure 4 and Figure 7 As shown, when the third motor 604 is started, it drives the third gear 605 to rotate through its output shaft. The third gear 605 is meshed with the fourth gear 606, and the rotation of the third gear 605 is transmitted to the fourth gear 606 through the meshing. The fourth gear 606 is mounted on the second rotating shaft 603. As the fourth gear 606 rotates, the second rotating shaft 603 also rotates, thereby driving the second roller 602 to rotate. The second roller 602 rolls through the rotation of the second rotating shaft 603, pushing the moving assembly 6 to move along the groove 501 of the support beam 5.

[0046] Compared with direct motor drive of the rotating shaft, the gear transmission system can reduce friction and improve transmission efficiency. The gear meshing transmission method has high transmission accuracy, which helps the moving component 6 to move accurately in the groove 501 of the support beam 5. The use of the gear transmission system not only improves the movement accuracy of the moving component 6, but also increases the stability and durability of the entire system.

[0047] In some embodiments, the number of the second rotating shaft 603 and the number of the second rollers 602 are both multiple and matched one to one, and the multiple second rollers 602 are arranged at intervals in the length direction of the support beam 5.

[0048] When the mobile assembly 6 moves on the support beam 5, the multiple second rollers 602 are evenly distributed, which helps to share the weight and reduce the burden of a single roller. The rolling motion of the second roller 602 in the groove 501 of the support beam 5 can provide better guidance and stability due to the increase in the number of the second rollers 602. The third motor 604 transmits power to each second rotating shaft 603 through the engagement of the third gear 605 and the fourth gear 606, thereby driving the corresponding second roller 602 to rotate. The uniform distribution of the multiple second rollers 602 helps to improve the stability of the mobile assembly 6 on the support beam 5 and reduce shaking and vibration during movement. The multiple second rollers 602 share the weight and improve the carrying capacity of the mobile assembly 6, so that it can cope with heavier photovoltaic panels 2 or other equipment. Since the load is distributed on the multiple second rollers 602, the wear of a single roller is reduced, thereby extending the service life of the second roller 602 and the second rotating shaft 603. The uniform arrangement of the multiple second rollers 602 and the high efficiency of the gear transmission system enable the mobile assembly 6 to move faster and more smoothly.

[0049] In some embodiments, there are multiple suction cups 9 , and the multiple suction cups 9 are arranged in a matrix on the mounting frame 8 .

[0050] The suction cup 9 generates suction through vacuum or other means to firmly adsorb the photovoltaic panel 2, ensuring that the photovoltaic panel 2 will not move or fall off during the replacement process. The suction cups 9 arranged in a matrix can be adjusted according to the size and shape of the photovoltaic panel 2 to adapt to photovoltaic panels 2 of different specifications. Multiple suction cups 9 can work at the same time, which improves the efficiency of adsorbing the photovoltaic panel 2 and reduces the replacement time. The suction cups 9 arranged in a matrix can select suction cups 9 in different positions for operation as needed, which increases the flexibility of replacing the photovoltaic panel 2. This design can adapt to photovoltaic panels 2 of different sizes and shapes, and improves the versatility and adaptability of the equipment. Multiple suction cups 9 adsorb photovoltaic panels 2 at the same time, which can provide higher stability and ensure that the photovoltaic panel 2 will not shift due to insufficient suction at a single point during the replacement process.
